Recently, Valentian (Suzhou) Teaching Equipment Co., Ltd. successfully delivered the PT500MINI mechanical failure test bench and PT580 water pump failure test bench to Pangang Steel. These two advanced experimental equipment will ensure the predictability of the equipment in the steel industry
Play a key role in the training of maintenance fault diagnosis, helping enterprises improve their equipment management level, reduce equipment failure rates, and ensure stable production operation.
Introduction to Delivery Equipment
The PT500MMINI transmission system diagnostic simulator is a highly integrated and functional device. It can simulate various common types of mechanical faults, providing rich learning and research materials for the technical personnel of Binxin Iron and Steel. For example, through a specially designed structure, it is possible to simulate the misalignment fault between the motor and the gearbox. By making an angle misalignment relative to the gearbox shaft, it simulates the misalignment situation caused by installation or long-term operation in actual production; By adjusting the fixing bolts at the bottom corner of the motor, it is easy to simulate the motor installation loosening fault, causing the motor to produce loose vibration phenomenon; In terms of simulating shaft friction faults, the friction type is set to contact sliding friction, which highly reproduces the real fault state. On the gear pool model, the large medical wheel of the experimental platform has double row teeth, which can be directly shifted to the faulty gear for simulating faults such as cracks, broken teeth, pitting, wear (hidden increase between teeth), etc., and only one gear is marked. Enterprises can choose any type of fault to display according to training requirements. To display multiple faults, they only need to open the gearbox and replace the gear. The simulation of rolling bearing faults is also convenient, as it can simulate rolling elements, cages, domestic and foreign faults. By quickly replacing the bearing with a bearing seat installation unit, it can be easily switched to a healthy bearing and restore normal operation, making it convenient for technicians to compare and learn. In addition, the simulation function of impeller rotor faults is also excellent, which can simulate faults such as imbalance, blade deformation, and blade cracks. By quickly replacing the blades, the impeller rotor fault experiment can be completed without disassembling the impeller, greatly saving operation time and cost. At the same time, balance weights can be installed at any angle on the rotor to achieve dynamic balance testing and meet diverse experimental needs.
PT580 Transmission System Diagnostic Simulator
The PT580 mechanical fault simulator is mainly used for simulating and diagnosing various faults of centrifugal pumps. It is equipped with an efficient and energy-saving ABB three-phase AC motor with a power of 2.2 kilowatts, paired with a 220V AC frequency converter. The frequency range of the transformer is 0-599Hz, and the rated input is 380-480V, which can stably drive the entire experimental system. The experimental platform consists of a motor, frequency converter, coupling, support bearing, water circulation pump group, pipeline, cut-off width, water tank, pointer pressure gauge, operating variable control module, faulty bearing, faulty impeller, etc.
This experimental platform can conduct multiple experiments, helping the technical personnel of Bingxie Steel to gain a deeper understanding of the principle and diagnostic methods of centrifugal pump faults. For example, observing and testing the cavitation phenomenon in centrifugal pumps, which is a common problem affecting the performance and service life of centrifugal pumps in actual industrial production; Simulate support bearing faults, including domestic, foreign, ball bearing, cage, comprehensive faults, etc., to comprehensively display the types of bearing faults; Presenting the phenomena of impeller imbalance, impeller wear, and impeller deformation, intuitively reflecting the impact of impeller failure on the operation of the water pump: observing the phenomena of slow water filling, low water outlet pressure, non compliant flow rate of the centrifugal pump, and interruption of the centrifugal pump pipeline after discharge, which are all practical problems that may be encountered in production; By analyzing the characteristics of centrifugal pump operation vibration through vibration analysis, understanding and interpreting the frequency latent characteristics of faulty components, and using computer dynamic analysis method to test fault signals, scientific data support is provided for fault diagnosis. During the delivery process and service support, Valentian Company demonstrated a professional and efficient service attitude. Starting from the production and manufacturing stage of the equipment, strict quality control is implemented to ensure that every component meets high standard requirements. In the transportation process of the equipment, professional packaging and transportation plans are adopted to ensure the safety of the PT500MINI mechanical fault simulator and PT580 mechanical fault simulator during transportation, avoiding equipment damage caused by bumps, collisions, and other reasons. After the equipment arrived at Pangang Steel, Valentian's technical team rushed to the site for the installation and commissioning of the equipment as soon as possible. With rich experience and professional skills, the technicians quickly completed the installation of the equipment and conducted detailed debugging of various functions to ensure that the equipment can operate normally and simulate various fault states accurately and stably. At the same time, in order to enable the technical personnel of Pangzi Steel to master the operation of equipment and fully utilize its functions, Valentinian's technical team also conducted comprehensive and in-depth training. The training content covers equipment operation methods, fault simulation settings, data collection and analysis, etc. Through a combination of theoretical explanation and practical operation, technical personnel can quickly grasp the key points of equipment use, laying a solid foundation for subsequent training on predictive maintenance and fault diagnosis of equipment.
The importance of the stability of equipment in the steel production process is crucial to the significance of Bingxin Iron and Steel. Once critical equipment malfunctions, it not only causes production interruptions and increases maintenance costs, but may also affect product quality and bring huge economic losses to the enterprise. And equipment pre maintenance and fault diagnosis training can help technicians detect potential faults in equipment in advance, take timely measures for maintenance and repair, and avoid equipment failures. The introduction of the PT500MINI machine vibration simulator and PT580 machine vibration simulator provides an ideal practical platform for the training of predictive maintenance and fault diagnosis of equipment at Panzhihua Iron and Steel. Technicians can simulate various obstacles that may occur in actual production on the experimental platform, recite the secrets of frequent faults, purchase and analyze data, deeply learn the methods and techniques of abortion diagnosis, and improve their professional skills. For example, by using the PT5OOMINI machine vibration simulator to simulate a broken tooth fault in a cargo ship, technicians can intuitively observe the vibration and noise changes of the equipment in the fault state, and use relevant sensors to collect data. They can analyze the fault diagnosis knowledge they have learned to identify the cause and solution. On the PT580 machine vibration simulator, technicians can conduct repeated experimental research on the cavitation fault of centrifugal pumps, understand the conditions and development process of cavitation, and its impact on pump performance, so as to take timely measures to prevent the occurrence of cavitation faults in actual production.
By using these two experimental devices for systematic training, the technical team of Pangang Steel will be able to diagnose equipment failures more accurately and quickly, develop reasonable maintenance plans, improve equipment maintenance efficiency and quality, which will help enterprises reduce equipment failure rates, extend equipment service life, reduce production interruption time, improve production efficiency, enhance the competitiveness of enterprises in the market, and provide strong guarantees for the sustainable development of enterprises.
The successful delivery of the PT500MINI machine vibration simulator and PT580 machine vibration simulator is an important achievement of the cooperation between Valentian and Zhenpan Steel. In the future, both parties will continue to deepen cooperation and continuously explore the management of experimental equipment in the field of equipment management
More application scenarios in the field will jointly promote the improvement of equipment management level in the steel industry.
